1]

Given the resistance values and the voltage you are asked to calculate the current in the circuit. This circuit follows a simple OHM's law which states

V = IR.
Where R is the total resistance of the circuit
I is the current flowing through the resistance.

Since the resistance connection in the circuit is "SERIAL"
The total resistance of the circuit is

R = R1 + R2 = 10 + 10 = 20 ohm
V = 10 V

I = V/R = 10/20 = 0.5 amps

Since the circuit connection is "SERIAL" current through R1, R2 and the ammeter are all the same. Hence the answers ...

#### Solution Summary

1) For the circuit below find:

a) The current through R1.
b) The current through R2.
c) The current at the ammeter.
